The Schedule referred in these Letters Patent and making part 0f the same.

Be it known that I, MAR'ILN WEAvER, miller, of

` East Earl township, in the county of Lancaster, and

State of Pennsylvania, have invented a new and iinproved Arrangement for Regulating the Feed for Millstones; and I do hereby declare that the following is a full, clear, and exact description ofthe construction v and operation of thesame, reference being had to the `accompanying drawings, making a pait'of this specification, in which-' Figure I is an elevation or section of my improvement in place in the eyeof the runner G; H, the bedi stone; R, the rhyne; S, the spindle; I, the ease; J, a

board over the opening of the case, as in vcommon use. Figure 2, the outer capl or vessel, which sets upon the rhyue, and fills the eye of the stone, or runner G.

Figure 3 shows theinside bottom ofthe cup A, with the spout-openings a', and central elevated disk B, and

raised curved beaters b. f'

Figure 4 shows the manner in which the spouts or oval tubes a of A enter or pass down between the horns of the rhyne R orl its open angles.

Figure 5 shows an inner open ring, D, (nearly df v l like diameter of the vesselA,) having slotted ears E ou two sides, by which it is `aiixed by binding-screws, and made adjustable onl the crossboard J, g. 1.

Figure 6 shows an ordinary silent feed, `in which ,ther-eisV no novelty.

The nature of my invention `consists in providing `the eye of a millstone, or runner with a device that l will prevent the material to be ground from sticking to the sides of the eye or from forming clogs or lumps, as frequently happens, causing the 4eye to ill `and run over, and causing such an increase of speed on the -runner as to burst' the stone. Y

To enable others skilled in the artvto make and use my invention, a brief explanation, in addition lto the descriptive reference of the drawings, will Suice.

'lhe metallic vesseLA, with its `four spouts a, and bottom, B, are set into the eye of the stone, so as to lill the saine from the rhyne to the top surface. The tubes a project obliquely downward between or through the open angles of the oross-bars It of the rhyne to within a short distance of the bed-stone.

A cast-iron ring, D, iig. 5,' is set within this outer `case or vessel A, allowing only sufficient play'for the outer vessel to revolve freely around it. This ring D is stationary, and provided with four (more or less) flanges or beaters, d, attached to the inner circumferi ence, and extending toward the centre. There are also two elongated ears, E, with an open slot, e, for a binding-screw, by which this ring D is adjusted within the box or case A the desired height from the bottom, B, and attached to a board, J, over the feed-opening in the case I, iig. 1. y

The ordinary silent feed F, fig. 6, attached by ears f to the aforesaid board J, and adjusted over the central disk B, may be used with said' ring D, or the common damsel in its stead.

The central curved beaters b and the anges d will n agitate the materials, and work them to the several spouts, and' convey the same between the runner and bed-stone with certainty, and prevent all danger of cloggingso as toarrest the proper delivery, but, on the contrarysecure a uniform, certain, and regular feed, and thereby obviate the possibilityof stones being bursted from a stoppage of the feed, and the extra high Speed of the runner induced by being thus suddenly relieved'from the necessary `supply to keep up the check on the runner.

Having lost Several stones by bursting from this cause, I-was led to experiment, to prevent such an acsident, which resulted in the invention of the device herein setforth, and a test for some mouths has satisfied me of its value and eiciency.

I am not aware that such a tubulated ease A and ring D were ever before used in the manner set forth, either with the ordinary damsel or silent feed.

I do not claim a receptacle situated within the eye of the runner-stone, and provided with lateral or conducting-tubes and an iuterior'cyliuder, furnished with wings or beaters, for such is shown in the patent of John Nairn, October 6, 1868; but

The combination and arrangement of the external cup A with its conductors a a a, central elevated disk B, and curved beaters b b b, internal ring D', provided with anges d d d d and slotted ears E c, all suspended within the eye of the .runner Gr, and operated as and for the purpose herein shown and described.
